Accused murderer Keith Luke thinks he is the “most important person in the world” and an “anti-Christ” who wants to kill himself and then come back from death as a serial killer, a psychologist testified for the defense on Friday.

“Some people are meant to be killers when they are born,” Luke once told a doctor during one of his hospitalizations, his medical records showed.

Forensic psychologist Ronald Ebert – the only witness to take the stand on Friday – was called to support the defense argument that Luke is not criminally responsible for his actions on Jan. 21, 2009.

On that date, testimony has shown, the self-proclaimed white supremacist gunned down two people and raped and shot a third victim who survived as part of a violent crime spree against non-whites.

Ebert testified that in his medical opinion Luke knew these acts were illegal but was not criminally responsible because of his mental illness.

“It is my opinion that he could not conform his behavior to the requirements of the law because of his delusions,” Ebert testified on Friday.

Defense attorney Joseph Krowski Jr. asked Ebert if he had any doubt in that statement.

“None” said Ebert, who said he interviewed Luke in 11 two-hour sessions since 2010.

In her cross-examination, assistant district attorney Donna Reardon pressed Ebert to explain why Luke was able to conform to the law on other occasions in an “ethnically diverse city” – such as when he visited a gym every day – but wasn’t able to control himself on Jan. 21, 2009.

“He was under the influence of his mental illness,” said Ebert.

About 4,500 pages of psychological evaluations of Luke were presented to the jury of seven men and eight women in Brockton Superior Court.

The dozens of doctors who evaluated Luke between ages 15 and 19 described mental illnesses that included schizophrenia, bipolar disorder, manic depression, antisocial personality disorder and symptoms including delusions, hearing voices and having cannibalistic, homicidal and suicidal tendencies, the records show.

On Friday, Luke showed little emotion as he sat in the courtroom while the history of his mental health was described. The smirk he has worn throughout the trial was not seen.

Surrounded by his usual contingent of seven court officers, Luke spent more than a half-hour writing on a piece of yellow paper from a legal pad.

There was only a small news media presence and few viewers in the gallery on Friday.

Jurors were shown images Luke drew through the years of hospitalization that included the devil and people being decapitated, hung and cooked.

Luke once told a doctor all he wanted in the world was to be the supreme ruler and kill, torture and eat people, Ebert testified.

He was obsessed with his mother to the point where he became so jealous of her cat that he put it in a suitcase and threw it into a river, Ebert testified.

Page 2 of 2 - Luke was hospitalized from age 15 to 19 until he was eventually deemed “in remission” in 2004, Ebert testified. His next hospitalization was in 2008 after he threatened to kill his mother. Six months later, the killings occurred for which he is on trial.

Ebert said never in any of the medical records did he see mention of Luke having racist tendencies.

Luke, now 26, is on trial for killing Selma Goncalves, 20, and Arlindo Goncalves, 72, who are not related, and attacking a third victim who survived and testified against him this week.
